fix missing spaces in Graphviz configure options

[jfgrimm]

currently, easyconfigs do the following:

configopts += '--with-javalibdir=$JAVA_HOME/lib'
configopts += '--with-expatincludedir=$EBROOTEXPAT/include --with-expatlibdir=$EBROOTEXPAT/lib'
configopts += '--with-zincludedir=$EBROOTZLIB/include --with-zlibdir=$EBROOTZLIB/lib'

since there are no spaces at the end or start of the strings, these just get glued together into options like --with-expatlibdir=$EBROOTEXPAT/lib--with-zincludedir=$EBROOTZLIB/include

(created using eb --new-pr)

Hmm, local build failure was with libGLU:

== 2024-01-23 15:54:24,857 build_log.py:171 ERROR EasyBuild crashed with an error (at easybuild/base/exceptions.py:126 in __init__): cmd " ./configure --prefix=/eb/maint/software/libGLU/9.0.3-GCCcore-12.3.0 " exited with exit code 127 and output:
/bin/bash: ./configure: No such file or directory
 (at easybuild/tools/run.py:682 in parse_cmd_output)

Could be yet another CentOS 7 thing?
